Summary
This quote suggests that having a large brain alone does not equate to having true knowledge and understanding. A large brain can easily be filled with useless or superficial information, making it appear knowledgeable on the surface but lacking depth and substance. Conversely, a small brain, taken metaphorically to represent a humble and receptive mind, can be truly enriched with valuable knowledge and wisdom. It highlights the importance of quality over quantity when it comes to acquiring knowledge.
